Barking up the wrong tree for performance.This REALLY needs to be changed. Allow no resistor. The values of resistance are all up and down the board. If resistors are mandatory, hand picking boots will rear its ugly head and some diy guys will be lost.
Tell me what you think the resistor is doing? The mixture is burning right, so what harm is a resistor doing? There must be a spark at the spark plug, the engine is running, and this idea that a hotter spark is available without the resistor, and the hotter spark will make more power, well, it's just not true.
It takes a certain amount of voltage to jump the gap, the moment that voltage is reached at the plug, the plug fires, resistor or not, no difference.
And yet people will ignore anything I say about air density. They will ignore what I say about jetting. Worse yet, they dismiss me. I don't race LTO, so what can I know, as if that had anything to do with air density and jetting.Al I have a feeling it is more about the "perceived advantage" than about the actual performance gain itself
I have an idea that fuel economy and emissions are a big reason for some of those changes.To jump the gap is the key.
Test the spark of the resistor at .025 then .060.then test the spark of a non resistor at .065 - .075.
It may not be more power but it does help with less fouling and a larger spark.
This is why auto makers have gone to hotter spark systems and larger plug gaps.
There is no standard part.Why Cant this be checked with a OHM Meter ?
That is why I went to work on the issue.I agree with Bennie and for the cost of good Ole common sense . I have replaced many boots and have seen no performance gain. This is one of those rules they don't need to be a stickler on besides taking a chance on breaking a person's part in tech. Realize ,no performance gain ,a replacement part that most likely won't have the resistor that doesn't do anything. ,do we or would you really want to be dq'd over something as silly as this
